Java Rest service how to do POST and get a zip file back

I have a url that I want to post to that takes a JSON string as the request body, and in the response I am expecting a zip file.  Can someone show me how to do this?  I tried WebTarget but couldn't get it to work.  Thanks.

What REST implementation are you using?

I was call a GET service method:

        WebTarget target =;
        Builder builder = target.request();
        try {
            Response response = builder
                    .header("Content-Type", "application/json")
            return Response.ok(response.getEntity()).header("Content-Type", "multipart/x-zip").header("Content-Disposition", "attachment;").build();
        } catch (Exception exp) {
            logger.error(exp.getMessage(), exp);
            return Response.serverError().build();

But now I need to change that to a POST.

Can you post the full code, you seem to have client side and server side code all mixed in together?
